Unlike the US and many European countries, Denmark has laws that cap the number of pigs per farm and put a ceiling on the total number of pigs allowed to be raised in the country, because

"Influenza [in pigs] is closely correlated with pig density," said a European Commission-funded researcher studying the situation in Europe. As such, Europe's rapidly intensifying pig industry has been described in the journal Science as "a recipe for disaster." Some researchers have speculated that the next pandemic could arise out of "Europe's crowded pig barns."

An expert in flu virus evolution says confining pigs and poultry in cramped bunkers, near each other, with human staff between them that never rotates is a recipe for crossbreeding truly nasty, persistent viruses that potentially jump from animals to humans.

Washington's answer is spin: calling the recent flu outbreak a series of letters and numbers instead of "swine flu," which offends the pork industry.
